{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays a week of temperature data in degrees Celsius for cities worldwide, sourced from Data Canvas - Sense Your City. Each city’s temperature over time is drawn as a smooth, multi-hued path using `d3.line`, `curveBasis`, and `d3.nest`. The SVG rendering uses `d3.scaleTime`, `d3.scaleLinear`, and `d3.scaleOrdinal(schemeCategory10)` for axes and colors, while a custom `colorLegend` function maps city names.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/11f2302b410341a498691c0f2a347290?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
